Embodiment Construction

[0046] The invention discloses a button, a keyboard, a keyboard control method and device, and an input device. The key point of the invention is that the key length of a part of the keyboard can be changed. The specific method for changing the key length can include: setting the keycap of the button as a magnetic A keycap, and a magnetic field generating device is set under the magnetic keycap. When the magnetic field generating device is energized, the generated electromagnetic field generates a magnetic force on the magnetic keycap, thereby changing the height of the key, so that the magnetic field generating device of each key can be controlled. The power-on or power-off can achieve the purpose of controlling different keys on the keyboard to distinguish them by height changes.

Abstract

The invention provides a key, a keyboard, a keyboard control method and a device thereof and an input device. The key comprises a magnetic keycap, a contact disposed opposite to the magnetic keycap, and a magnetic field generating apparatus disposed below the magnetic keycap and capable of allowing variations in relative distance between the magnetic keycap and the contact. The keyboard includes the keys. The keys, the keyboard and the input device allow the necessary keys to be raised or sunken relative to unwanted keys for a user in an application through a key control method and a device thereof, so that the user does not touch the unwanted keys by mistake while using the keys and user experience is enhanced.

Description

technical field [0001] The invention relates to the field of computers, in particular to a button, a keyboard, a keyboard control method and device, and an input device. Background technique [0002] The keyboard is an unobtainable input device in the personal computer. When the computer is running the application program, the user can press the keys on the keyboard to input instructions to operate the running application program. Usually, for different application programs, the keys on the keyboard that need to be used are different. Generally, there are always some keys that are not needed in the current application program running mode. For example, when a user plays a game, they only need some keys to control the direction, but the number keys and most of the letter keys are unnecessary. At present, when encountering such a situation, the method of disabling the functions of unnecessary keys is generally adopted. , but this method can only ensure that the unnecessary ke...
